What is the 7 electromagnetic spectrum?
The electromagnetic spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV) light, X-rays and gamma-rays.
What are the 7 types of electromagnetic spectrum and their uses?
What are the 7 types of electromagnetic waves and their uses
- Radio waves: Communication.
- Microwaves: Heating and data transmission.
- Infrared waves: Used in remote control and imaging applications.
- Visible light: Help us see everything around us.
- Ultraviolet Waves: Useful in the study of galaxies.
How do you remember the order of light spectrum?
ROYGBIV (in reverse VIBGYOR) is commonly used to remember the order of colors in the visible light spectrum, as seen in a rainbow. (red, orange, yellow, green, blue, indigo, violet).
How do you read electromagnetic spectrum?
From longest to shortest wavelengths, it includes radio waves, microwaves, infrared light, visible light, ultraviolet light, X rays, and gamma rays.
Which color has the fastest speed?
colour red
When light passes through a prism, they get bent by different amounts and come out all spread out instead of mixing up. The colour violet travels the slowest, so it is on the bottom and the colour red travels the fastest so it is on the top.
Why is the sun red?
To conclude, the sun appears red because red light penetrates the atmosphere more effectively than other colors, which is precisely why those celestial bodies that are visible from Earth have a reddish or orange hue, depending on the time of day and their place in the sky!
What is the slowest color?
Violet
Violet travels the slowest so it is on the bottom and red travels the fastest so is on the top. This is because what is called the index of refraction, (the ratio of the speed of light in a vacuum to the speed of light in a material), is increased for the slower moving waves (i.e. violet).
